Abstract
In some embodiments, a method includes sending an authentication request to a client device to obtain a utilization code in response to a request from the client device to access data. The utilization code is uniquely associated with the client device. The method includes obtaining an authentication response including the utilization code from the client device and authenticating the client device if the utilization code matches a utilization identifier stored in a database. The method includes generating an encryption key using a seed based at least in part on the utilization code and encrypting the data with the encryption key to generate encrypted data and sending, when the utilization code matches the utilization identifier stored in the database, the encrypted data to the client device without requiring a user of the client device to login.
